2. The combination, With the knetter-frame and knetter operating shaft, of two levers affixed to an oscillating shaft j ournaled in said frame, a short arm on said shaft for oscillating both levers, one of said levers being adapted to tuck and disengage the bindingcord in combination with the, rotary knetter andthe other lever adapted for actuating the cord-clamping mechanism, the rotary `knotter and cord-clamping mechanism journaled in the knetter-frame on the same side as the levers, and the knetter-operating Wheel having the segmental gear and cam on the same side of the wheel for operating both levers andknotter, substantially as described.

3. In a knotting mechanism for grain-bin ders, an oscillating lever affixed to a horizontal shaft journaled in main knetter-frame between the knetter and main knetter-operating shaft, and crossWise to both the knotter-shaft and said main knetter-operating shaft, and having said lever adapted for tucking and disengaging the binding-cord, in combination With` a rotary knotter and a knife moving with said lever for severing the the opposite end of same shaft, to Which is aiiixed the tucker-lever, and adapted to overhang and operate the cord-clamping mechanism, all arranged and adapted for operation in combination with a single knetter-op- Wheel on main knetter-operating vvers mounted upon a common journal in said knetter-frame, all on the same side of the wheel, oneof said levers having a notched foot rigidly formed to its lower or free end,'a cord-severing knife on said foot, and having said foot adapted to tuck and disengage the binding-cord in combination with the knotter, and the other lever provided at its free end with mechanism `for actuating the cordclamping mechanism, substantially as described.

5. The combination, With the knetter-frame and knetter-operating shaft, of the rotaryv knetter journaled in said frame, the rotary cord-clamping mechanism, two oscillating levers moving upon a common journal, also j ournaled to said frame, one of said levers being provided at its free end with paWl mechanism for intermittently rotating the cordclamping mechanism and the other lever being provided at its free-end with mechanism 'for4 controlling yand disengaging the bindingcord in combination with the rotary knetter and the single Wheel upon said shaft, proyvidedwvith a cam andsegment-gear upon the upon a common oscillating axis, and means, `substantially as described, connecting said foot and lever with and operating them positively from a cam upon said main. knot-teroperating shaft.
